MATCHER.

SPECIFICATION forming part of Letters Patent No. 431,796, dated July 8, 1890. Application filed May 1, 1889. Serial No. 309.163. (N model.)

To all whom it may concern.-

Be it known that I, EDWIN BENJAMIN, of South Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Matchers, of which the following is a specification.

My invention has for its objectthe provision of improved devices for matching lumber, whereby the planer may be adapted to match either one or two pieces at a time and may be changed with facility from one to the other kind of work.

Another object in view is to so construct and arrange the heads for matching the inner edge of the lumber that they shall operate in the same way as those 011 the outsidethat is, shall rotate on a vertical axis and present their cylindrical faces to the lumber, securing thereby the well-known advantages of finish and smoothness of work resulting therefrom over that produced by cutter-heads rotating on a horizontal axis and presenting their end faces to the lumber, while at the same time the cutters shall occupy as little of the width of the planer as possible, the width of lumber workable being thereby increased correspondingly.

My invention is further concerned with the provision of facilities for the adjustment of said cutter-heads. I

My invention consists in the parts and combinations described and claimed.

In theaccompanying drawings, Figure 1 is a side view of a planer-bed having my im proved matching devices connected therewith, so much of the other parts being shown as is necessary to the proper understanding of the invention. Fig. 2 is a vertical longitudinal section of the right-hand end of Fig. 1, the point of view being on the opposite side from that of Fig. 1. Fig.3 is an end elevation corresponding to Fig. 2.

Upon'the planer-bed A, Fig. 1, are mounted in the usual manner the cylinder-housings B and the feed-roll housings C. To the latter a girder D, Figs. 2 and 3, is fastened, said girder forming a portion of the fixed frame work and afiording a support for the saddles EF,in which are journaled the matcher-head spindles G H. The saddles E F are secured to the girder D on opposite sides by bolts IJ, on which they may be rotated when the bolts are loosen ed.

Braces K L, slotted at their ends, as shown, and extending from the girder to the saddles, aid in holding the latter firm when adjusted. The saddles are so placed that a line through the center of the matcher-heads M N is nearly parallel with the line of travel of the lumber, one being almost exactly behind the other. They are slightly out of line, however, so that each head will operate on one board only.

To secure the exact adjustment of the matcher-heads M N, the saddles E F are made in two parts, so that they are adjustable both Vertically and horizontally. As they are both alike in structure, only one E is fully shown and described.

One part c is fastened by the bolt I to the girder D, said bolt passing through a slot in the part c in the same manner as shown in dotted lines in Fig. 3 with reference to bolt J. The head of bolt I forms a bearing for a screw 0, collars o 0 preventing end motion of the same. The end of screw 0 is tapped into the saddle E. By turning the screw 0 the saddle can thus be movedin or out the exact amount desired. To secure vertical adjustment, the part a, carrying the journal-boxes for the spindle G, is fitted in slides s s in the part e, which isfastened to the girder. Lugs P and Q are integral with the parts e and 6', respectively, and a screw R, like screw 0, is journaled in one lug and tapped into the other, so that turning the screw will raise or lower the part c.

hen it is desired to work only one Width of lumber at a time, one or both cutter-heads M N may be moved out of the way by loosening the braces K L and bolts I J and swinging the upper ends of the saddlesE Foutwardly. The position of the bolts I J outside of the perpendicular passing through'the cutter-heads is such as to produce an upward movement to the cutter-heads, which gets them out of the way by a comparatively slight movement. The matcher-heads so located and adjusted may be driven in various ways, but a preferred mode is shown in Fig. 1.

Pulleys S T are located on the upper end of the spindles G H. Said pulleys derive their motion through quarter-twist belts S T from pulleys U V on the counter-shaft 'X, which stands parallel to the side of the planer. Said counter-shaft derives its movement from one of the main driving-shafts of the planer, as Y, through the intermediate shaft Z at right angles to the side of the planer, abelt S ,connecting shafts Y and Z, and a quarter-twist belt T connecting shafts X and Z. I have shown the shafts X and Z as supported by a separate pedestal Z and standards Z but it is of course immaterial how this is done.

I make the matcher-heads as small as posisible, and by hanging them as described the two heads occupy scarcely more of the width of the machine than one would do. There is therefore no space wasted.

The matching-heads for the outer edges of the boards may be made in any of the usual ways, and as the present invention is not concerned with them they are not shown. 1

I claixn 1. The combination, in a matcher adapted to work two pieces of lumber at the same time, of two cutter-heads rotatable on vertical axes placed relatively to each other in a line nearly parallel to the line of travel of the lumber, each cutter-head being adapted to dress an inner edge of one piece of lumber, substantially as described.

2. The combination, in a matcher, of a cut (er-head rotatable on a vertical spindle, a saddle supporting said cutter-head spindle, and a pivotal fastening whose axial line is at one side of the axial line of the cutter-head,whereby the cutter-head is raised clear of the bed by rotating the saddle on its pivot, substantially as described.

3. The combination, in a matcher, of a matcher-head rotatable on a vertical spindle,

a saddle carrying said spindle, said saddle formed in two parts adj ustably fitted to each other by slides, an adjusting-screw j ournaled in one of said parts and tapped into the other, a pivotal bolt passing through a slot in said saddle andsecuring the latter to the framework, a'nd an adj QStiIIg-SOIGW journaled in said pivot-bolt and tapped into the saddle,

all combined substantially as set forth.

4. The combination, in a matcher adapted to work two pieces of lumber at once, of matcher-heads rotatable on vertical spindles placed relatively to each other in a line nearly parallel to the line of travel of 'the lumber, and of a driving-gear for said spindles comprising a counter-shaft parallel to an intermediate shaft placed at right angles to the side of the planer, and belts and pulleys connecting said shafts with each other and with a main driving-shaft and the matcher-head spindles, respectively, substantially as described.

5. The combination, in a matcher adapted to work two pieces of lumber at once, of cutter-heads M N, rotatable on vertical spindles G H placed relatively to each other in a line nearly parallel to the line of travel of the lumber, saddles E F, composed of the parts e and e, adjustable vertically and horizontally by screws R and O, and pivotally screwed to the frame-work by bolts I J, and driving-gear for said cutter-head comprising shafts X and Z, respeci ively, parallel to and at right angles to the side of the matcher and pulleys thereon, and belts S T S T communicating power from a main driving-shaft to said cutter-heads, substantially as described.
